Hallo there, I want to flash my Sony DDU1621 DVD-ROM. I have a very old version (S1.6). I tried using the .exe file I downloaded from Sonyâ€™s official site, but I got a really strange message that â€œthis is the incorrect firmware versionâ€ or something, and the device stopped working for a while. Fortunately it â€œrecoveredâ€ after 2 reboots. And I donâ€™t get it. What does it mean wrong version? Is there a way to choose a wrong version? I just choosed the last one…

Anyway, I decided to use mtkflash. I read all the faq and help I could get, I want to be SURE before I try anything that could damage the drive, so I thought I should post for a question and a â€œverificationâ€. I downloaded mtkflash v1.80 and firmware vS4.1 from this page( http://etna.rpc1.org/mt/index.html ) -by the way, what is the difference between rpc1 & rpc2- My DVD is connected to Secondary MASTER. So I guess all I have to do is create a bootdisk, copy mtkflash and binary files on the disk, boot and run:

MTKFLASH 3 W /B /M filename.BIN
,right???

The thing is that there 2 binary files in the zip file, bide00.bin and bide01.bin. Which one do I use in the command line??
